The rPlaylist Stack is an advanced mp3 audio playlist player. It uses HTML5 audio in browsers that support HTML5 with mp3 files. In other browsers, it falls back to an invisible Flash component making it work cross browser. This also means that this player will work perfectly on iDevices too, like the iPhone or iPad.
What's so special about this stack is that you can add your mp3 files by simple drag and drop operation. No need to fumble around with page assets and cryptic path URLs. You can also prelisten your audio files directly in RapidWeaver. Of course you can also just link to hosted mp3 files or even a mp3 streaming server like shoutcast. The player is fully customizable with colors and your own icons.
